What accessories do hotels need when customizing in seafood pool and their functions?

The customization in seafood pool is actually to simulate a small environment similar to the ocean by artificial methods, so that seafood can survive in it. If natural seawater is used, it will be simpler. The circulating water pump can make the water in seafood pool flow endlessly through the filtration system. However, if artificial seawater is used (that is, tap water and sea crystal are mixed in different proportions), three points must be paid attention to: first, the new pond must be disinfected and neutralized by acid and alkali, and the commonly used drugs are oxalic acid, potassium permanganate and bottle opener; Second, it is necessary to let tap water stand for more than 24 hours, or use chemical dechlorination methods (such as dechlorination water) to remove chlorine; Thirdly, sea crystal (quality is very important) is a special salt for cultivating seafood, which cannot be replaced by inferior sea crystal or ordinary salt. In addition to sea crystals, cultivating seafood generally requires the following equipment: seawater concentration meter (also known as salinity meter) is used to prepare and monitor the salt concentration of artificial seawater in seafood pool; Thermometers are used to measure the water temperature in seafood pool. Because most seafood lives in cold waters and is very sensitive to temperature changes, it is necessary to continuously monitor the water temperature in seafood pool. Refrigeration equipment uses professional refrigeration equipment to reduce the water temperature in seafood pool; The function of heater is opposite to that of refrigeration equipment, which can provide heat energy and make seafood have a suitable temperature in winter; Naturally oxidized in the airflow. This is the equipment for making oxygen in seafood pool.
